Rasheed Wallace is contemplating a return to the NBA, according to multiple reports.

Wallace, 37, hasn't played since the 2010 NBA Finals as a member of the Boston Celtics.

A league source who has talked with Wallace recently told Yahoo! Sports, which first reported the story, that the 6-11 Wallace is “serious” about a return to the NBA this season. However, no teams contacted by Yahoo! Sports reported that they had any contact with Wallace, or his representative.

The big question with Wallace, given his status as one of the most skilled big men of his era and ability to shoot and defend, is whether he's in shape to play. It's the same question that dogged him during his final season.

"Guys like Rasheed, with his skills, his game won't totally fall apart just like that," an Eastern Conference executive told CSNNE.com. "But you have to wonder, how much can he give you right away? And how long will it take him to get not just in shape, but basketball shape? I suspect whatever team he goes to, if he does come back, will be a team that won't need him to come in and make an impact right away."

The Celtics, as noted by CSNNE, would have to release a player—possibly center Greg Stiemsma or swingman Sasha Pavlovic—if they wish to sign Wallace.
